Foods that contain MSG (monosodium glutamate) often cause allergies in people. People usually complain of itchy skin or swollen eyes, etc. Amongst other causes, allergies are quite frequently the cause of sinusitis.

How do Allergies cause Sinusitis?

When allergens such as dust, pollen, dander, pets or grass get into your sinuses they irritate and inflame the mucus membranes. This causes your body to produce an excess amount of mucus to flush the irritant out and results in even more swelling of the mucus membranes and blockages. These blockages then cause the mucus within the sinuses to become stagnant and provides an environment in which bacteria can thrive. This bacteria then causes a sinus infection.

MGS containing foods?

Many food items contain Monosodium glutamate (MSG). This ingredient is used as an additive in foods. An additive is added to food to give it a better taste and to make it look good to eat.

MSG  is usually found in foods such as canned products especially soups, many fast foods, instant meals, frozen meals, barbecue sauce, ketchup, stock cubes and frozen sea food.
